Colla B7000 25ml trasparente per schermi, cornici e hobby

La B7000 destaca davant els cianoacrilats (super glue) per la seva flexibilitat un cop curada, resistència a les vibracions i capacitat de formar unions desmuntables, cosa que facilita futures reparacions. A més, no deixa residus blancs ni danya materials sensibles. Això és clau per a l’electrònica, on la rigidesa pot danyar components o crear tensions en pantalles sensibles al tacte.

No es recomana l’ús de B7000 sobre silicones, escuma de polietilè (foam), materials extremadament porosos o superfícies impregnades amb olis. També pot mostrar baixa adherència sobre PTFE i polipropilè (PP) si no es lija o prepara la superfície. Sobre metalls molt llisos pot requerir un tractament previ per a una màxima adherència.

L’assecat superficial es produeix en uns 6 minuts (a 23°C i 50% HR), però el curat total triga entre 24 i 48 hores depenent del gruix i de les condicions ambientals. El rang operatiu de temperatura és entre -35°C i 90°C, sense presentar falles estructurals evidents dins d’aquest marge.

B7000 està classificada com a no tòxica i no corrosiva; tanmateix, es recomana manipular-la en zones ventilades i evitar el contacte prolongat amb la pell o la inhalació directa de vapors. No és inflamable un cop curada. Tot i que compleix normatives estàndard per a coles domèstiques, no disposa de certificació alimentària ni mèdica específica.

B7000 stands out over cyanoacrylates (super glue) for its flexibility once cured, resistance to vibration and ability to form removable bonds, which makes future repairs easier. It also does not leave white residue or damage sensitive materials. This is key for electronics, where rigidity can damage components or create stress in touch-sensitive screens.

B7000 is effective on metals, glass, ceramic, stone, wood, fabric, leather, PVC, ABS, nylon and rubber, among others. It can be used on PE and PP, although these materials have low surface energy and adhesion may be weaker than on other plastics. For critical applications with PE/PP, testing before final use is recommended.

The initial setting time for B7000 is approximately 3-6 minutes (do not move bonded parts), reaching functional strength after 6 hours. Full curing is typically achieved in 24-48 hours, depending on layer thickness and ambient humidity.

Yes, dried B7000 bonds can be painted or sanded. The adhesive is flexible and retains its properties in humid environments or under light to moderate vibration, making it suitable for portable electronics and moving parts. However, extreme exposure can reduce its service life.
